Abstract:

Current portable computers and PDAs fail to truly become part of our daily
lives in the sense that we need to stop what we are doing and expend
conscious effort to use them.
They also do not have the situational awareness that they
should have: while they are not being explicitly used,
they are unable to remain attentive to possible ways to help the user.

Environmental technology in the form
of ubiquitous computing, ubiquitous surveillance,
and smart spaces, has attempted to bring multimedia computing seamlessly
into our daily lives, promising a future world with cameras and
microphones everywhere, connected to invisible computing, always attentive
to our every movement or conversation.
This raises some serious privacy issues. Even if
we ignore these issues, there is still a problem of user-control, customization,
and reliance on an infrastructure that will not (and probably should not)
become totally ubiquitous.

In response to these problems,
a personal, wearable, multimedia computer, with
head-mounted camera(s)/display, sensors, etc.
is proposed for use in day-to-day living within the
surrounding social fabric of the individual.
Examples of practical uses include:
face identification (memory aid for names),
way-finding via sequences of freeze-frames, shared visual memory/environment
maps, and other personal note-taking together with visual images.

Anecdotal personal experiences, over several years of use, are
reported, and privacy issues are addressed, in particular, with a
discussion of how personal `smart clothing' has counteracted
or at least reached a healthy balance with environmental surveillance.
